banana-rdf is a library for RDF, SPARQL and Linked Data technologies
It can be used with existing libraries without any added cost. There is no wrapping involved: you manipulate directly the real objects. We currently support Jena, Sesame and Plantain, a pure Scala implementation.
banana-rdf emphasizes type-safety and immutability, so it can come
with some cost when the underlying implementation is very mutable (I'm
looking at you, Jena and Sesame). We try to keep a clear distinction
between the core concepts and the enhanced syntax that Scala can give
itself is defined as a record of types. Implementations just have to
plug their own types. And because types alone are not enough, we
typeclass, which defines the mandatory operations that an RDF
does the same for SPARQL.
banana-rdf, you get
Diesel, a nice DSL to build and navigate
within pointed graphs (graphs with a pointer to an inner
node). You also get an abstraction for graph stores
GraphStore), which do not have to be SPARQL engines
SparqlEngine). Of course, you can serialize and deserialize
most of the RDF syntaxes (RDFa and JSON-LD will come soon).
banana-rdf introduces the concept of binders, which let you
bridge the Scala and RDF worlds. Most of the common datastructures are
already available, and you can even map your own classes. Unlike usual
ORM techniques, this does not rely on annotation or reflection.
Until we write thorough documentation, the best place to understand what you can do is to go through the test suite.
You only need a recent version of Java, that's all:
$ git clone email@example.com:w3c/banana-rdf.git $ cd banana-rdf $ ./sbt
